SUBHARINE SIGNAL AND AIR SUPPLY DEVICE Filed Feb. 25. 1928 2 Sheets-Sheet 2 WITNESSES INVENTOR ATTORNEY Patented Sept. 17, `1929 sUnMAnINn `sreiriinAND AIR-SUPPLY, DEVICE ,Applicationfled February 25,` 1928;.Sreri'a1` L'No1 257,085.l I y i `This invention relates to submarine signalling devices, and particularly to an improved signalling device `which is capable of presentingmeans `whereby. air or food may be supplied to sunken' submarines. i

Anotherr objectof the invention is to ron y 4,1allthe parts therebene'ath are ina waterf lcompartmentand, therefore," will 'not C vide an attachment yfor submarines whic is capable of presenting a signal at the surface when the submarine issubmerged, whereby f communication may be readily provided between the interiorl of the submarine and pern sons atthe surface ofthe water.

A still further object yof the lnventionis `to n provide for submarines not only a signalling device for indicating the location of a sunken submarine, but means whereby a cable or other elevating means may be connected to the submarine for lifting-purposes. f

In the accompanyingdrawings- `Figure 1 is aperspective v'ew, of a-small part of a submarineillustrated as being below the surface, togetheriwth signalling means embodying the invention shown appliedto the submarine; on f f Y i Figure 2 is an enlarged sectional view through Figuref1,-approximately on line 2-e2. ,Figure 8 is y,a vfragmentary sectional view through Figure 1, approximately on line 3%3.
